First Look: SRAM GX Drivetrain

SRAM brings affordable 1x11 with 2x11 and 2x10 options

SRAM GX 2×11 – Available August 2015

If 1×11 is the group most lust for, 2×11 is the answer to the call of many who long for a lower gear. There’s a few out there (ahem, Europe) who seek a higher gear as well for the extended periods of fire road or pavement.

But one thing many don’t realize is that 1×11 is a bit of a compromise. Often, low gear is compromised because the romance with simplicity and handlebar real estate is so rewarding. The front chainring on a 1×11 drivetrain is best when it is customized for one’s power, weight, terrain and wheel size. Put it a formula and hopefully a 32, 34 or 36 number pops out as your ideal match. If not, you have to man up, get strong or get a 26 or 28 tooth front ring. Those work but they don’t have a good high gear range and pedaling efficiency is compromised with such small rings.

So for those riders where 1×11 is a stretch, there is now a solution, 2×11. This 2x solution has the fabled 10×42 in the back so you can hang out in one chainring all day. But when you finally run out of gearing in the back cluster, you have more. Plus the front rings are not so far apart that front shifting is difficult under load or abrupt.

The downside of course is you have a front shifter and derailleur again and lose the magic of Narrow-Wide chain retention and management. But hey, now you have a choice during purchase and you’re not locked in during the life of your bike.
